I have P3dv4 . Using current 757 just downloaded new version a week ago. I have no sounds in the cockpit except the engines sounds. No flap, buttons, switches, tcas, alarms, warnings etc etc etc.....my drivers up to date . I have Realtek drivers . Whats the problem. All my other aircraft TFDI other Flythemaddog another company all have sounds working perfectly. Anyone ??? thank u
